Hundreds of service manuals for electronic organs and digital keyboards. Some sound equipment and other types.   3630 models of keyboards, organs and other equipment. 60 different companies. 

PLEASE CHECK THE MANUFACTURERS LIST BELOW FOR YOUR EQUIPMENT BRAND.   

Aeolian, Aiphone, Alesis, Allen & Heath, Allen, Avante Garde, Baldwin, Bogen, Casio, Conn, Crest, Crouse-Hinds, Crumar, DOD, Edirol, Ensoniq, Farfisa, Fender, Dalanti, General Music, Gulbransen, Hammond, Howard, Johannus, Kawai, Kimball, Korg, Kurzweil, Leslie, Lowery, Mass-Rowe, Mackie, Mesa-Boogie, Motion Sound, Panasonic, Peavey, PianoDisc, Pianola, Protek, QSC, REILS, Rodgers, Roland, Samick, Samson, Shure, Spirit, Studiomaster, Suzuki, Tascam, Technics, Telex, Thomas, Trek II, Van Koevering, Victrola's, Viscount, Wurlitzer, Yamaha.  

It would not be possible for me to list all of the model numbers, but I have an exact computer data base of them.  They are identified by Brand and MODEL NUMBER.  The serial number is useless.  Every piece of equipment came with a model number sticker somewhere.  Many of the keyboards and organs have a sticker up under the keyboard.  You need a flashlight, lay on the floor and look up under it.  If not there - it WILL be somewhere.  I can not identify one by description, serial number or any other means, I MUST HAVE THE MODEL NUMBER.  

Once you have the Model Number, e-mail me with the brand and model number.  I will check the list and e-mail you back with availability and price.  The manuals will vary in price from $15 to $50 depending upon size, with the majority being $25 or less.  As I am retired now and not actively in my former business, I do not check e-mails every day, but I will get back to you.  DO NOT PAY FOR ANYTHING UNTIL I GIVE YOU A PRICE.  

Because of how e-bay's pricing system works, I have listed a buy now price of $50 and will accept bids above $15.  THE PRICE WILL BE WHAT IS SHOWN IN MY EMAIL TO YOU.
Thanks for looking, Ed
